Gaze-contingent visual presentation technique with electro-ocular-graph-based saccade detection
Junji Watanabe, Taro Maeda, Hideyuki Ando
Article No.: 6
DOI: 10.1145/2207216.2207217

When a single column of light sources flashes quickly in a temporal pattern during a horizontal saccade eye movement, two-dimensional images can be perceived in the space neighboring the light source. This perceptual phenomenon has been applied to...

Evaluating the effectiveness of orientation indicators with an awareness of individual differences
Tina Ziemek, Sarah Creem-Regehr, William Thompson, Ross Whitaker
Article No.: 7
DOI: 10.1145/2207216.2207218

Understanding how users perceive 3D geometric objects can provide a basis for creating more effective tools for visualization in applications such as CAD or medical imaging. This article examines how orientation indicators affect users' accuracy...

Parametric time-frequency representation of spatial sound in virtual worlds
Mikko-Ville Laitinen, Tapani Pihlajamäki, Cumhur Erkut, Ville Pulkki
Article No.: 8
DOI: 10.1145/2207216.2207219

Directional audio coding (DirAC) is a parametric time-frequency domain method for processing spatial audio based on psychophysical assumptions and on energetic analysis of the sound field. Methods to use DirAC in spatial sound synthesis for...

Real-time adaptive blur for reducing eye strain in stereoscopic displays
Laure Leroy, Philippe Fuchs, Guillaume Moreau
Article No.: 9
DOI: 10.1145/2207216.2207220

Stereoscopic devices are widely used (immersion-based working environments, stereoscopically-viewed movies, auto-stereoscopic screens). In some instances, exposure to stereoscopic immersion techniques can be lengthy, and so eye strain sets in. We...
